Red is not always Brandi Glanville's color. "The Real Housewives of Beverly Hills" star, 40, shared a not-so-glamorous side of herself via Twitter on Wednesday -- in which the former model's now-famous face is red and raw as she bites hesitantly on her fingernail. It turns out that the "Drinking and Tweeting" author suffers from melasma, a skin discoloration condition, and a doctor's recommendation of laser treatment was harsher than expected.

After concerned fans asked how the reality star burned herself, Glanville explained further, "Doctor said he could get rid of my melasma. It was [too] hard for my skin. Still healing, its been depressing #skinobsessed."

Being "obsessed" with her skin might even lead to a post-Hollywood career in the "beauty biz," Glanville joked. "I have a skin obsession and when all this Hollywood stuff is over I will def be in the beauty biz!"
